Definitions

  • the invention relates to a dynamoelectric machine with a stator and a rotor with a closed cooling circuit.
  • an electric machine With a housing, with a stator and a rotor and a water cooling, wherein the laminated core of the stator is shrunk into a housing and rests on the entire package length in the housing. Between inner shell and outer shell, a cooling coil is provided, wherein the air duct provided radially outside a closed system.
  • the electrical machine has a cooling jacket of a stator, which has axially extending cooling ribs.
  • a surface-cooled, closed electric machine is known, are provided in the air guide elements in the interior of the dynamoelectric machine to guide the air flow before entering the axial cooling channels of the stator via a winding head of the winding system.
  • a dynamoelectric machine in which a cooling jacket surrounding the stator is provided on the air gap side facing away from the stator with substantially axially extending AufEnglishung the cooling jacket, wherein the recesses are provided with cooling hoses and wherein at least axial portions of this recess to the back of the stator are open.
  • the present invention seeks to provide a dynamoelectric machine, which provides for a sufficient cooling, especially for confined spaces on the one hand and at the same time does not pose a threat in tight spaces for maintenance personnel, such as. are present in wind gondolas.
  • the solution of the problem is achieved in that on the outer circumference of the laminated core of the stator, so at the yoke back support points of the inner shell are having radially inwardly facing substantially axially extending cooling fins that do not rest against the yoke back.
  • the temperature of the housing for maintenance personnel is now uncritical, since the cooling jacket thus only has the maximum allowable cooling temperature.
  • the inner jacket to the outer periphery of the stator axially extending cooling fins, which thus increase the heat transfer surface of the cooling jacket.
  • These ribs and thus the inner shell are based on the outer circumference of the stator only at predetermined contact points, but do not reduce the cooling capacity.
  • These cooling fins are welded or cast on the inside of the inner shell.
  • the entire length of the housing of the stator is used to recool the internal air. Furthermore, now the entire outer surface of the inner shell can be lapped with cooling water, so that the cooling efficiency is significantly increased.
  • Liquid circulates in the now formed cooling jacket on the outer surface of the inner casing between inner casing and outer casing.
  • the cooling channels of the cooling jacket run either spirally or meandering around the interior of the dynamoelectric machine. In order to obtain the best possible cooling jacket, outer jacket and inner jacket are joined together in a thermal or hydraulic shrinkage process.
  • the basic structure now shows that the liquid cooling is radially outward, while the cooling fins are arranged for re-cooling the circulating internal air between yoke back of the stator and the liquid cooling jacket.
  • the surface temperature of the dynamoelectric machine in operation never becomes higher than the maximum allowable cooling water temperature of the dynamoelectric machine. This will additionally heat up the environment and other equipment, especially in a runaway nacelle prevented. Hot surfaces on the dynamoelectric machine are thus also avoided and maintenance personnel are less at risk.
  • radial cooling channels are created by means of a pressure finger arrangement, that is to say special intermediate elements, between the partial laminated core of stator and rotor.
  • these cooling channels of rotor and stator are aligned in the radial direction, so that the air flow from an axially extending cooling passage of the rotor and entering the radial cooling passage of the electromagnetic air gap enters a radial cooling slot of the stator and then on the outer periphery of the laminated core of the stator again emerges and bounces on the cooling jacket and is cooled back there.
  • the already heated air quantities emerging radially from the rotor 3 pass through the air gap of the dynamoelectric machine into the respectively opposite radial cooling slots of the stator 1. There, the air is further heated and exits radially from the stator 1. If the stator 1 has axially extending cooling channels, a mixing of the air quantities also occurs in the radial cooling slots of the stator 1.
  • the axial extent of the cooling jacket 11 should correspond at least to the axial extent of the stator 1. Much more suitable is the expansion of the cooling jacket from one bead end to the other or even over the entire axial length of the dynamoelectric machine, i. from one end shield 12 to the other.
  • FIG. 2 shows in a partial cross section of the structure of the dynamoelectric machine, wherein the rotor 3 is positioned with its partial laminated core 4 on the shaft 7.
  • Each partial laminated core has cooling channels 15, which are advantageously aligned axially.
  • the laminated core of the stator 1 connects radially outward, which has grooves in which a winding system is located.
